中文摘要

直流微电网因其高效率和高电能质量备受关注,但快速可靠的过流与短路故障保护仍是技术难点。本文提出一种基于耦合电感的固态断路器(SSCB),通过减少组件数量,实现了快速、无电弧的故障清除,为直流配电系统的保护提供了高效解决方案。

English Abstract

DC microgrids have gained importance for their high efficiency, no need for synchronization, high power quality, and potential to reduce greenhouse gas emissions. Ensuring reliable and fast protection against over current and short-circuit faults is considered to be a challenge even to date. Solid-state circuit breakers (SSCBs) offer a promising solution, providing rapid and arc-less fault clearin...
